The relationship between quality of infant-mother attachment and infant competence in initial encounters with peers.

18-month-old infants and their mothers were observed in the Ainsworth strange situation (SS) in order that security of attachment might be assessed. Infant dyads were created for observation in unstructured peer interaction according to their SS classification (security of attachment). Focus was on the subgroups within the securely attached (B) category. Results indicated a relationship between quality of infant-mother attachment and infant peer competence. The B1 and B2 infants engaged in more frequent and more sophisticated interaction with peers than did the B3 and B4 infants, who intensely sought proximity and contact with their mothers in the peer session just as in the SS. The B1 and B2 infants engaged in more distal interaction with their mothers and were more sociable with the peers' mothers and with the stranger in the SS. Implications of individual differences in quality of attachment for the development of social competence and social relationships are discussed.     

Fathers and mothers at play with their 2- and 3-year-olds: contributions to language and cognitive development

Father-child and mother-child engagements were examined longitudinally in relation to children's language and cognitive development at 24 and 36 months. The study involved a racially/ethnically diverse sample of low-income, resident fathers (and their partners) from the National Early Head Start evaluation study (n=290). Father-child and mother-child engagements were videotaped for 10 min at home during semistructured free play, and children's language and cognitive status were assessed at both ages. Fathers' and mothers' supportive parenting independently predicted children's outcomes after covarying significant demographic factors. Moreover, fathers' education and income were uniquely associated with child measures, and fathers' education consistently predicted the quality of mother-child engagements. Findings suggest direct and indirect effects of fathering on child development.     

Human Relations: The Cornerstone of a Roeper Education

This article traces the evolution of a moral philosophy curriculum originally taught by George A. Roeper in the earliest years of The Roeper School. The first author, a student at The Roeper School in the 1960s and 1970s, describes the impact of the class George Roeper called “Human Relations” on her life. Returning to the School as a parent and trustee, she had the opportunity to re-create for current students the experience of the Human Relations class in a workshop, liberally borrowing material from a philosophy class taught by Harvard political philosopher Michael Sandel. In the second part of the article, a current English teacher at The Roeper School and attendee at that workshop discusses how she was inspired to revise her literature courses to incorporate the moral philosophy approach of George Roeper and Michael Sandel.     

Educating Young Educators: A Pedagogical Internship for Undergraduate Teaching Assistants

Although undergraduates have long held a role as teaching assistants for introductory science courses at liberal arts colleges and universities, educational institutions often do not provide these students with opportunities to explore science teaching and pedagogy. At Brandeis University, we designed an internship course to help increase the motivation, understanding, and knowledge of teaching pedagogy for undergraduate teaching assistants that is offered concurrently with their teaching responsibilities. Weekly sessions with faculty mentors are guided by readings in current science education literature, and throughout the semester students are asked to develop new course material based on the pedagogical frameworks discussed. To evaluate the effectiveness of this course, we surveyed students at the close of the semester. We found an overall increase in student confidence levels with regard to teaching and better awareness of the difficulties faced in science education. All students who participated in the course expressed interest in participating in future educational internships. We believe that the Educating Young Educators internship has the potential to be a catalyst for personal and professional growth from a novice into an informed young educator.     

Doing an effective job? Measuring the impact of casework

This article describes an initiative to evaluate the impact of educational psychologists’ (EPs’) casework. Previous studies have often focussed on evaluating processes or reducing outcomes to measurable units. The authors argue that qualitative research methods can be used to illuminate EP effectiveness. They describe a real world and proportionate methodology, crucially aimed at supporting self‐reflection and development. An evaluation of this initiative showed that it can demonstrate EP impact and has validity for individual and service improvement. Implications, including the need to face up to less than positive feedback, are discussed.     

The role of pelvis-thorax coupling in controlling within-golf club swing speed

Pelvis-thorax coordination has been recognised to be associated with swing speed. Increasing angular separation between the pelvis and thorax has been thought to initiate the stretch shortening cycle and lead to increased clubhead speed. The purpose of this study was to determine whether pelvis-thorax coupling played a significant role in regulating clubhead speed, in a group of low-handicap golfers (mean handicap = 4.1). Sixteen participants played shots to target distances determined based on their typical 5- and 6-iron shot distances. Half the difference between median 5- and 6-iron distance for each participant was used to create three swing effort conditions: “minus”, “norm”, and “plus”. Ten shots were played under each swing effort condition using both the 5-iron and 6-iron, resulting in six shot categories and 60 shots per participant. No significant differences were found for X-factor for club or swing effort. X-factor stretch showed significant differences for club and swing effort. Continuous relative phase (CRP) results mainly showed evidence of the stretch shortening cycle in the downswing and that it was more pronounced late in the downswing as swing effort increased. Substantial inter-individual CRP variability demonstrated the need for individual analyses when investigating coordination in the golf swing.     

Statistical analyses in the physiology of exercise and kinanthropometry

Research into the physiology of exercise and kinanthropometry is intended to improve our understanding of how the body responds and adapts to exercise. If such studies are to be meaningful, they have to be well designed and analysed. Advances in personal computing have made available statistical analyses that were previously the preserve of elaborate mainframe systems and have increased opportunities for investigation. However, the ease with which analyses can be performed can mask underlying philosophical and epistemological shortcomings. The aim of this review is to examine the use of four techniques that are especially relevant to physiological studies: (1) bivariate correlation and linear and non-linear regression, (2) multiple regression, (3) repeated-measures analysis of variance and (4) multi-level modelling. The importance of adhering to underlying statistical assumptions is emphasized and ways to accommodate violations of these assumptions are identified.     

Changes in locomotive rates during senior elite rugby league matches

Abstract

The aim of this study was to quantify the changes in locomotive rates across the duration of senior elite rugby league matches. A semi-automated image recognition system (ProZone 3, ProZone®, Leeds, England) was used to track the movements of 59 players from six teams during three competitive matches. The players were classified into one of four positional groups: props (n = 9), back row (n = 9), pivots (n = 14) or outside backs (n = 27). Players' movements were classified as low, high or very high intensity running and reported as locomotive rates (distance covered per minute played) for successive quarters of each match. Analysis of variance revealed that only the outside backs showed a significantly lower overall locomotive rate during the final quarter compared to the first (P < 0.05). However, locomotive rates for high and very high intensity running during the final quarter were significantly lower (P < 0.05) than the first quarter among outside backs, pivots and props despite no change in the rate of involvements in contact. On the basis of these findings, it is suggested that high and very high intensity running locomotive rates may be more affective methods of detecting fatigue during competitive matches than overall locomotive rate.
